The Aussie sisters were top of the bill for the final of the ‘X Factor’ in Australia and took the roof off with a performance of their Christmas duet ‘100 Degrees’, cheered on by their mum and dad, who were in the studio audience.

Bless!

The last time the siblings shared a stage on TV was waaaay back in 1986 when they performed a cover of ‘Sisters Are Doing It For Themselves’ on the Aussie variety show ‘Young Talent Time’

And this being Kylie and Dannii, their ‘X Factor’ performance was never going to be an understated affair.
